Two interesting videos I ran across.

The first shows all nuclear armed nations and order that they first got the bomb:

The other shows every nuclear test done worldwide since 1945, up through 1998:

I didn't realize till now just how many nukes have been exploded in tests, roughly 2,000. It was a bit unsettling to watch. Essentially, the earth has already survived a nuclear war.

The total nuclear weapons already exploded is almost equal to the total current U.S. nuclear arsenal.
